Johannesburg - Four men who allegedly killed Mozambican Emmanuel Sithole at the weekend are expected to appear in the Alexandra Magistrate's Court on Tuesday.
Pictures of the 35-year-old being hit with a wrench and stabbed on a street in Alexandra on Saturday morning were published in the Sunday Times. Sithole died in the photographer's car outside Edenvale hospital.
Three of his alleged attackers were arrested on Sunday after police offered a R100,000 reward for information which could lead to their arrest and conviction. A fourth suspect was arrested on Monday night.
"The suspects were arrested in Alexandra with the help from the members of the community," Lieutenant Colonel Lungelo Dlamini said.
Dlamini said police were investigating whether Sithole's death was linked to the deaths of at least six people during xenophobic violence in the past week.
According to Dlamini, Sithole was a street vendor killed during an argument with a customer.
"The information we have is that he was a street vendor who had an argument with a customer, who allegedly stabbed him and he was taken to hospital where he died. Whether the matter was an attack on a foreign national forms part of the investigation," he said.
